Overview

SF-10/250 Skid-Mounted High-Pressure Air Compressor

The SF-10/250 skid-mounted high-pressure air compressor is an industrial-grade reciprocating piston compressor designed for continuous and stable high-pressure air supply up to 25 MPa.G.
It is engineered for pipeline testing, pigging, gas lift operations, and other demanding industrial applications requiring reliable, oil-free compressed air.

As a factory-manufactured, skid-integrated system, the SF-10/250 offers high efficiency, fast installation, and long-term operational stability in harsh environments.


Key Specifications

  • Medium: Air (100% purity)

  • Flow Rate: 10 m³/min (600 Nm³/h)

  • Inlet Condition: Atmospheric pressure & temperature

  • Discharge Pressure: Up to 25 MPa.G

  • Drive Power: 145 kW motor (diesel or electric optional)

  • Cooling Method: Full air-cooled design

  • Compression Type: Single-stage, single-acting piston compressor

  • Installation: Integrated skid-mounted (plug-and-play)


Core Advantages

High-Pressure & High Stability

Designed for sustained operation at ≤25 MPa, ensuring stable output for long-duration testing and industrial processes.

Skid-Mounted Plug-and-Play Design

All major components—including compressor, motor, piping, instrumentation, and electrical systems—are pre-installed on a single skid base, allowing commissioning within 4–6 hours with minimal on-site work.

Energy-Efficient Operation

Optimized compression design and power matching reduce long-term energy consumption by 8–12% compared with conventional models under similar operating conditions.

Durable Industrial Construction

  • Heat-resistant gray cast iron cylinders

  • Forged steel crankshaft for high tensile strength

  • Low vibration and low noise operation

Designed for continuous duty in oilfields, construction sites, and industrial plants.


Advanced Cooling & Lubrication Design

The SF-10/250 adopts a dedicated full air-cooling system, ensuring effective heat dissipation for both compressor cylinders and coolers:

  • High-speed cooling fan (1980 r/min)

  • Belt-driven transmission with adjustable tension

  • Enclosed air duct for controlled airflow

A dual lubrication system combines pressure lubrication for high-load components and splash lubrication for auxiliary parts, extending service life by approximately 30% while reducing maintenance frequency.


Oil-Free Air for Sensitive Applications

An independent cylinder isolation design prevents lubricating oil from entering the compression chamber.
This makes the SF-10/250 especially suitable for oil-sensitive operations, such as:

  • Pipeline pressure testing

  • Pigging operations

  • Gas lift systems

  • Industrial processes requiring clean compressed air


Typical Applications

  • Pipeline pressure testing and pigging

  • Oilfield gas lift operations

  • Industrial projects requiring high-volume, high-pressure air

  • Infrastructure and energy engineering projects


Customization & Non-Standard Design

The SF-10/250 is a custom-engineered solution, not a fixed standard model.
We provide application-specific designs based on:

  • Required flow rate, pressure, and air purity

  • Operating environment and ambient conditions

  • Installation type (fixed, mobile, cabin-mounted)

  • Drive mode (electric motor or diesel engine)

Available structural configurations include D / M / S / W / V / Z types, with air-cooled, water-cooled, or mixed cooling options.


Compliance & Manufacturing Strength

  • Designed according to PED / EN standards (project-based)

  • Multiple patented compressor technologies

  • Complete factory testing before delivery

  • Suitable for global industrial and EPC project


Use Case FAQ – SF-10/250 High-Pressure Air Compressor


Q1: Why is the SF-10/250 suitable for pipeline pressure testing?

Answer:
The SF-10/250 is suitable for pipeline pressure testing because it delivers stable compressed air up to 25 MPa.G, features an oil-free compression design, and operates reliably under long-duration, continuous workloads. Its skid-mounted structure allows rapid deployment on pipeline construction sites, making it ideal for hydrostatic and pneumatic testing operations.


Q2: Why choose a skid-mounted air compressor for pipeline and oilfield projects?

Answer:
A skid-mounted air compressor like the SF-10/250 offers fast installation, easy transportation, and high structural stability. All major components are pre-installed on a single skid base, reducing on-site assembly time and minimizing vibration and misalignment during operation—critical advantages for oilfield and pipeline projects.


Q3: Can the SF-10/250 be used for pigging operations?

Answer:
Yes. The SF-10/250 provides high-volume, high-pressure clean air, making it suitable for pipeline pigging operations. Its consistent pressure output ensures stable pig movement, while the oil-free air design prevents contamination inside the pipeline.


Q4: Why is oil-free air important for gas lift operations?

Answer:
Oil-free air prevents contamination of pipelines, valves, and downstream equipment. The SF-10/250 uses an independent cylinder isolation structure to eliminate oil carryover, ensuring clean compressed air that meets the requirements of gas lift systems and sensitive oilfield equipment.


Q5: Is the SF-10/250 suitable for continuous operation in oilfields?

Answer:
Yes. The SF-10/250 is designed for continuous-duty operation, featuring a robust crankshaft, heat-resistant cylinders, optimized cooling, and low-vibration performance. These characteristics ensure stable operation under harsh oilfield conditions and extended runtime.
